Copenhagen has given us the chance to face climate change with honesty  

James Hansen has an article in The Guardian welcoming the demise of the Copenhagen conference - Copenhagen has given us the chance to face climate change with honesty. Points awarded to anyone who knew what "fugacious" meant before reading this...

Last weekend's minimalist Copenhagen global climate accord provides a great opportunity. The old deceitful, ineffectual approach is severely wounded and must die. Now there is a chance for the world to get on to an honest, effective path to an agreement.

The centrepiece of the old approach was a "cap-and-trade" scheme, festooned with offsets and bribes – bribes that purportedly, but hardly, reduced carbon emissions. It was analogous to the indulgences scheme of the Middle Ages, whereby sinners paid the Church for forgiveness.

In today's indulgences the sinners, developed countries, buy off developing countries by paying for "offsets" to their own emissions and providing reparation money for adaptation to climate change. But such hush money won't work. Yes, some developing country leaders salivated over the proffered $100 billion per year. But by buying in, they would cheat their children and ours. Besides, even the $100 billion hush money is fugacious. The US, based on its proportion of the fossil fuel carbon in the air today, would owe $27 billion per year. Chance of Congress providing that: dead zero. Maybe the UK will cough up its $6 billion per year and Germany its $7 billion per year. But who will collect Russia's $7 billion per year?

Most purchased "offsets" to fossil fuel carbon dioxide emissions are hokey. But there is no need to flagellate the details of this modern indulgences scheme. Science provides an unambiguous fact that our leaders continue to ignore: carbon dioxide from fossil fuel burning remains in the climate system for millennia. The only solution is to move promptly to a clean energy future.

The difficulty is that fossil fuels are the cheapest energy, if the price does not include the damage they do to human health, the planet, and the future of our children. "Goals" for future emission reductions, whether "legally binding" or not, are utter nonsense as long as fossil fuels are the cheapest energy. The Kyoto Protocol illustrates the deceit of our governments, which have not screwed up their courage to face down the fossil fuel industry. As the graph here shows, global fossil fuel emissions were increasing 1.5% per year prior to the 1997 Kyoto accord. After "Kyoto" emission growth accelerated to 3% per year. A few developed countries reduced their fossil fuel use. The only important effect of that was to slightly reduce demand for fuel, helping to keep its price down. The fuel was burned in other places, and products made were shipped back to developed countries.

As far as the planet is concerned, agreements to "cap" emissions, such as the Kyoto Protocol and the imagined Copenhagen Protocol, are worthless scraps of paper. As long as fossil fuels are the cheapest energy, they will be burned somewhere.
